論文概要:This dissertation provides a comprehensive evaluation of the environmental and economic implications of integrating Distributed Energy Resources (DER) technology in buildings. Amid rising global energy consumption and the challenges of climate change, the study highlights the critical role of renewable energy and DER systems in advancing sustainable energy solutions.

The research begins with an analysis of energy usage patterns and the environmental impacts of conventional energy sources, followed by an exploration of DER concepts, including microgrids and the optimization tool DER-PLAN. The core of the study focuses on hydrogen co-generation systems in detached houses, utilizing simulations to assess power and heat utilization, energy conservation, and battery regulation. A sensitivity analysis examines factors influencing optimal capacity and cost efficiency of residential power generation equipment.

Extending to a real-world application, the research evaluates DER-based energy infrastructure in the JONO area, analyzing capacity, operational patterns, and environmental and economic performance. Findings indicate that DER systems can improve operational efficiency by over 30%, reduce CO2 emissions by more than 30%, and deliver substantial environmental and economic benefits, despite high initial investment costs.

In conclusion, this dissertation underscores the potential of DER technology to mitigate environmental impacts and enhance energy efficiency in buildings. By advocating for "zero carbon blocks" and optimal energy resource utilization, the study offers a pathway for advancing sustainable energy infrastructure and achieving long-term decarbonization goals.
